The words below are not mine. They were written by Tal Ben-Shahar in his book The Persuit of Perfect. These two paragraphs illustrate how striving for perfection will never make us happy.
The Greek myth of Sisyphus tells of a man, the most cunning of mortals, who was punished for his pride and disobedience. Sisyphus was condemned by the gods to push a heavy rock up a mountainside and then watch it roll down again, repeating this process for all eternity.
Psychologically speaking, the Perfectionist is like Sisyphus. But whereas the punishment of Sisyphus was inflicted by the gods, the Perfectionist’s punishment is self-inflicted. No success or conquest, no peak or destination, is ever enough to satisfy the Perfectionist. When he reaches the summit of one mountain or another, when he achieves some form of success, there is no delight, no savouring – only another meaningless journey toward a destination that inevitably disappoints.
